项目摘要

Non-Technical AbstractThe Wisconsin Materials Research Science and Engineering Center addresses grand challenges in two areas of materials science and engineering: (1) how atoms and molecules move in liquids and glasses and (2) developing new forms of magnetism using ultrathin, atomically perfect membranes. Addressing the first challenge depends on combining new kinds of experiments with developments in artificial intelligence. Advances will have applications in creating new glasses for organic electronic applications like electronics displays and photovoltaics and in enabling new formulations of drug molecules into pills (or other forms) patients use. Addressing the second challenge involves using bending and stretching of membranes to disturb their regular pattern of atoms, creating new patterns in the distribution of magnetic poles on very short length scales of just tens of nanometers. Advances will have applications in information processing, including in high-speed, nonvolatile data storage, and in the emerging area of quantum computing. The Center also supports materials research infrastructure, including a new facility using ultrafast pulses of ultraviolet light to study materials, and partnerships with industry. To broaden participation in materials research, the Center runs an extended orientation program called Forward Fellows to jumpstart the graduate careers of first-generation, historically underrepresented, or other non-traditional students. It also seeks to inspire people to pursue careers in science and engineering through public outreach, including reaching economically disadvantaged people in partnership with service organizations and reaching blind and low vision people in partnership with the Wisconsin Council for the Blind and Visually Impaired.Technical AbstractThe Wisconsin Materials Research Science and Engineering Center addresses grand challenges in two areas of materials science and engineering: (1) mobility in glasses and supercooled liquids at the molecular level and (2) creation and control of nonequilibrium magnetic states in strained single crystal membranes. Research in the first area will utilize coherent electron nanodiffraction experiments to resolve local dynamics and physics-inspired machine learning to develop molecular-level understanding from simulations. Potential technological applications include glassy films of organic semiconductors with high molecular anisotropy for organic electronics and stabilization of drug molecules in the amorphous state for pharmaceutical preparations. Research in the second area builds on a unique materials platform of non-van der Waals single crystal membranes, subjected to strains and strain gradients to break crystal symmetries and induce novel magnetic states. Potential technological applications include stabilizing skyrmions or other spin textures for nonvolatile memory and increased efficiency quantum transduction from spins to light and vice versa. The Center also supports materials research infrastructure, including a new facility for ultrafast extreme ultraviolet absorption spectroscopy, and an industrial consortium to foster partnerships between companies and Center researchers. To encourage broader participation in materials research, the Center runs an extended graduate orientation and professional development program called Forward Fellows, designed to give first generation, historically underrepresented, or other non-traditional students a jump start on graduate school. The Center also seeks to inspire people to pursue careers in science and engineering through public outreach, including reaching economically disadvantaged people in partnership with service organizations and reaching blind and low vision people in partnership with the Wisconsin Council for the Blind and Visually Impaired.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

威斯康星州材料研究科学与工程中心致力于材料科学与工程两个领域的重大挑战：（1）原子和分子如何在液体和玻璃中移动，（2）利用磁性的原子完美膜开发新形式的磁性。解决第一个挑战取决于将新型实验与人工智能的发展相结合。这些进展将应用于为电子显示器和光电子学等有机电子应用创造新的玻璃，并使药物分子的新配方成为患者使用的药丸（或其他形式）。解决第二个挑战涉及使用膜的弯曲和拉伸来扰乱它们的原子规则模式，在几十纳米的非常短的长度尺度上创造磁极分布的新模式。这些进展将应用于信息处理，包括高速非易失性数据存储和新兴的量子计算领域。该中心还支持材料研究基础设施，包括使用紫外光超快脉冲研究材料的新设施，以及与工业界的合作伙伴关系。为了扩大材料研究的参与，该中心开展了一项名为Forward Fellows的扩展定向计划，以启动第一代，历史上代表性不足或其他非传统学生的研究生职业生涯。它还旨在通过公共宣传激励人们追求科学和工程事业，包括与服务机构合作接触经济弱势群体，与威斯康星州盲人和视力受损者理事会合作接触盲人和低视力人群。技术摘要威斯康星州材料研究科学与工程中心解决材料科学和工程两个领域的重大挑战：（1）分子水平上玻璃和过冷液体中的迁移率，以及（2）应变单晶膜中非平衡磁态的产生和控制。第一个领域的研究将利用相干电子纳米衍射实验来解决局部动力学和物理启发的机器学习，以从模拟中发展分子水平的理解。潜在的技术应用包括用于有机电子学的具有高分子各向异性的有机半导体的玻璃状膜和用于药物制剂的无定形药物分子的稳定化。第二个领域的研究建立在非范德华单晶膜的独特材料平台上，受到应变和应变梯度的影响，以打破晶体对称性并诱导新的磁性状态。潜在的技术应用包括稳定非易失性存储器的skyrmions或其他自旋纹理，以及提高从自旋到光的量子转换效率，反之亦然。该中心还支持材料研究基础设施，包括一个用于超快极紫外吸收光谱的新设施，以及一个工业联盟，以促进公司和中心研究人员之间的伙伴关系。为了鼓励更广泛地参与材料研究，该中心开展了一项名为Forward Fellows的扩展研究生定向和专业发展计划，旨在为第一代，历史上代表性不足的学生或其他非传统学生提供研究生院的跳跃式开始。该中心还旨在通过公共宣传，激励人们追求科学和工程事业，包括与服务组织合作，帮助经济上处于不利地位的人，以及与威斯康星州盲人和视力障碍者理事会合作，帮助盲人和低视力者。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准。
